Can't Get White Dimmer to Work Single Pole - Always On

White Series Smart Dimmer (VTM31SN)

Installed as a single pole switch. I can add to apple home. The LED switch light panel works. Issue is the lights always stay on. Regardless of of what I do with they pysical switch or the Home app. I can control the LED bar but not the main lights.

With the air gap safety open:

Ground to Neutral - 0.2V
Line to Ground - 120V
Line to Neutral - 120.5V
Ground to Load - 0.3V
Load to Line - 119.4V Load to Neutral - 0.13V

Any advice or thoughts? Thanks!



It sounds as if the Smart Bulb Mode is turned on.

Are you using Smart Bulbs?

Did you turn on the SBM?

If the answer is yes to both, then that’s the expected behavior. If it’s no and SBM is enabled, turn it off.

Enable Smart Bulb Mode

To enable Smart Bulb Mode on your White Series 2-1 Switch, hold down on the top part of the paddle (on) while simultaneously tapping the configuration button four (4) times (do not let go of the paddle when finished tapping the config button). Wait for the LED Bar to flash solid yellow (and then let go of the paddle) indicating the switch has enabled Smart Bulb Mode.

Disable Smart Bulb Mode

To disable Smart Bulb Mode on your White Series 2-1 Switch, hold down on the bottom part of the paddle (off) while simultaneously tapping the configuration button four (4) times (do not let go of the paddle when finished tapping the config button). Wait for the LED Bar to flash solid blue (and then let go of the paddle) indicating the switch has disabled Smart Bulb Mode.

That’s it! I do not have smart bulbs. So disabling that feature fixed it. Thank you!
